Abstract
The utility model discloses a composite insulating pipe connecting piece, which relates to the technical field of plumbing pipe fitting manufacturing, and comprises a sleeve body formed by surrounding two shells which are in butt joint, wherein a plurality of outwards protruded bent hooks isare arranged on two sides of one shell; openings of the hooks are inwards; and buckles buckled on the hooks are arranged on two sides of the other shell. Compared with the prior art, the composite insulating pipe connecting piece has the advantages that a pipe joint can be fixed with a composite insulating pipe only through buckling the butt-joint surrounding buckles of the two shells in place without other tools, so that the aims of simplicity, quickness, convenience, and time and labor saving are realized.
Description
Technical field
The utility model relates to water heating pipe fittings manufacturing technology field, especially a kind of folding shell for being fixed after the pipe joint insulation of compound thermal insulating pipe joint is processed.
Background technique
Carry out the various pipe networks such as heat supply, refrigeration with compound thermal insulating pipe and mat formation in the engineering, being connected between compound thermal insulating pipe and the various pipe joints is to adopt hot melt to take over; Way is, cuts (PPR) inner tube that one section outer tube and thermal insulation layer expose in the termination of compound thermal insulating pipe, and the outer wall of (PPR) inner tube and (PPR) pipe joint inwall respectively behind the hot melt, are plugged in together until fuse fully, cool off, solidify again; The pipe joint that welding is good is wrapped heat-preservation cotton, be contained in heat-preservation cotton and compound thermal insulating pipe is fixed outward with a pair of folding shell, insulation effect is played in the joint of compound thermal insulating pipe; The technological scheme of existing compound thermal insulating pipe straight-through connecting piece is: comprise by two shell docking enclosing the body that forms; The outer dual-side of described shell is provided with a plurality of outwardly little, and described little platform is provided with aperture.In use there is following deficiency in this complex heat-preservation tubular union technological scheme: want first cementing can manage it the location at the interface of two shells during installation, with tapping screw little of two shells carried out fasteningly again, need instrument, it is long that the loaded down with trivial details time is installed.
The model utility content
Technical problem to be solved in the utility model provides a kind of instrument that do not need, complex heat-preservation tubular union quick and easy for installation.
The technological scheme that the utility model technical solution problem adopts is: this all compound thermal insulating pipe link, comprise by two shell docking and enclose the body that forms, the dual-side of a described shell is provided with having contact with of a plurality of outwardly bendings, the described mouth of hook that has contact with inwardly, the dual-side of another described shell is provided with and is buckled in the described buckle that has contact with.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect: only need during installation that two shell docking are enclosed the buckle fastening and put in place, just pipe joint and compound thermal insulating pipe can be fixed, need not the instrument simple and fast, time saving and energy saving.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Embodiment's 1 as shown in Figure 1 and Figure 2 compound thermal insulating pipe straight-through connecting piece includes and comprises by the docking of two shells and enclose the body that forms, what the dual-side of a shell 1 was provided with a plurality of outwardly bendings has contact with 3, have contact with 3 the mouth of hook inwardly, the dual-side of another shell 2 is provided with to be buckled in and has contact with 3 buckle 4; The free flow coupling that welding is good is wrapped heat-preservation cotton, respectively shell 1 and shell 2 are contained in free flow coupling and one section outer fastening of compound thermal insulating pipe is fixed, then the seam crossing at shell brushes glue, has so just finished the insulation processing to the free flow coupling of compound thermal insulating pipe joint; Need not the instrument simple and fast, time saving and energy saving.
Embodiment's 2 as shown in Figure 3, Figure 4 compound thermal insulating pipe 90 degree bend connecting fittings include two shell docking and enclose the body that forms, what the dual-side of a shell 1 was provided with a plurality of outwardly bendings has contact with 3, have contact with 3 the mouth of hook inwardly, the dual-side of another shell 2 is provided with to be buckled in and has contact with 3 buckle 4; The 90 degree elbows that welding is good are wrapped heat-preservation cotton, respectively shell 1 and shell 2 being contained in 90 degree elbows fixes with the fastening outward of one section compound thermal insulating pipe, then the seam crossing at shell brushes glue, has so just finished the insulation processing to 90 degree elbows of compound thermal insulating pipe joint; Need not the instrument simple and fast, time saving and energy saving.
